Hunters’ preferences for engaging in control programs of introduced Eastern cottontails in Italy: a factorial survey approach

A review of volunteers’ motivations to monitor and control invasive alien species

People make an important contribution to the study and management of biological invasions, as many monitoring and control projects rely heavily on volunteer assistance. Understanding the reasons why people participate in such projects is critical for successful recruitment and retention of volunteers. We used a meta-synthesis approach to extract, analyze and synthesize the available information from 28 selected studies investigating motivations of volunteers to engage in monitoring and control of invasive alien species (IAS). Our findings show how motivations fit three broad themes, reflecting environmental concerns, social motivations, and personal reasons. An important outcome of this study is the description of motivations that are unique to the IAS context: supporting IAS management, protecting native species and habitats, and livelihood/food/income protection or opportunities. In addition, our study reflects on important methodological choices for investigating volunteer motivations as well as ethical issues that may arise in practice. We conclude with a set of recommendations for project design and future research on volunteer motivations in IAS contexts, emphasizing the importance of collaboration with social scientists.

“An American near Rome” … and not only! Presence of the eastern cottontail in Central Italy and potential impacts on the endemic and vulnerable Apennine hare

The eastern cottontail Sylvilagus floridanus has been introduced to Italy for hunting purposes since the 1960s. This species is currently present in northern Italy, with some small populations in Central Italy. Data for Central Italy are scanty, but they deserve research attention because this lagomorph is responsible for the spread of disease to an endemic vulnerable species, the Apennine hare Lepus corsicanus. In this work, we summarized the distribution of alien cottontails, over 50 years after their first releases, with special regard to areas where the endemic species is present. Eradication should be recommended where the alien species coexists with the endemic one.
